Will the US try to denuclearise North Korea by force?

The United States has rerouted several warships towards the western Pacific Ocean, after North Korea fired a ballistic missile into the Sea of Japan.

The Carl Vinson strike group, which includes a nuclear-powered aircraft carrier, was initially meant to be heading to Australia. Its new route is seen as a show of strength by the US, which is also putting pressure on regional powers.

President Donald Trump has spoken to Japanese Prime Minister Shinzo Abe about countering threats from North Korea.

And US Secretary of State Rex Tillerson says China has agreed that action must be taken.

To what lengths will Washington go to remove a potential threat?
